Super Gem are too large in the bust for most things. I've found some Model doll stuff fits Soom, but its hit and miss at times. I have a friend who has an SD16 body but I'm yet to see if her shoes would fit the soom heel feet.

Kawaii_mon, thanks for posting this comparison info; I found it very useful to see at-a-glance the differences, and have just been able to quickly buy some clothes for my incoming Beryl (second owner)!

As for the high-heeled shoes, the one pair of Volks shoes I have is a decent fit. The Super Gem's toes don't go down quite as far into the toe of the shoe as the SD16's, so long-term stability might be a slight issue, but the arch of the foot is similar, and the Super Gem's heel fits snugly into the shoe.

With pants... probably not. You'll see in my photos that the Super Gem girl is much more... moreso in the hips and thighs than the SD16G. Lengthwise, though, they're virtually identical.
